The invention belongs to the field of aviation technology undercarriage design, and relates to an energy conversion valve used for an undercarriage folding and unfolding system. When the main system works normally, the pilot electromagnetic valve in the energy conversion valve is not electrified, the energy conversion valve is located at the working position of the main system, at the moment, the load subsystem communicates with the main system and isolates the standby system, and the landing gear cabin door/landing gear actuator cylinder is normally retracted and released; when the main system breaks down, the standby system supplies pressure, a pilot electromagnetic valve of the energy conversion valve is powered on, the load subsystem communicates with the standby system, the main system is isolated, and an undercarriage cabin door/undercarriage actuator cylinder is released emergently. The two positions of the valve element are reliably isolated, and a single function fault is not leaked to another system.
本发明属于航空技术起落架设计领域,涉及一种起落架收放系统使用的能源转换阀。主系统正常工作时,能源转换阀中的先导电磁阀不通电,能源转换阀处于主系统工作位,此时负载子系统与主系统沟通,并隔离备系统,起落架舱门/起落架作动筒正常收放;当主系统存在故障时,备系统供压,能源转换阀的先导电磁阀通电,负载子系统与备系统沟通,并隔离主系统,起落架舱门/起落架作动筒应急放;阀芯两位间具备可靠隔离,单个功能故障不泄露至另一系统。
